[PATCH v2 3/3] doc: usage: cmd: reset: specify when the -edl option is available

[Quentin Schulz <foss+uboot@0leil.net>]

From: Quentin Schulz <quentin.schulz@cherry.de>

The option is only available when CONFIG_SYSRESET_QCOM_PSCI is enabled,
so let's make that explicit in the boot cmd documentation.

Due to the implementation in drivers/sysreset/sysreset-uclass.c
do_reset() function, all options to the reset command are passed to all
sysreset drivers' sysreset_ops.request_arg callback (including -w) which
is only available when CONFIG_SYSRESET_CMD_RESET_ARGS=y. -w, however,
works also without this option.

Fixes: ef06c5d76ff4 ("cmd: boot: Add '-edl' option to reset command documentation")
